Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Jack and jack stands, lug wrench, torque wrench, tire pressure gauge, alignment tool, and possibly a road force balancer.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting the vehicle.

2. Tire Inspection and Balancing

Remove the wheels using the lug wrench.
Inspect tires for bulges, cracks, or uneven wear. Replace if necessary.
Check tire pressure and inflate to recommended levels.
Mount the tires on a road force balancing machine to check for imbalance.
Balance tires as necessary and reinstall them to the vehicle.

3. Suspension and Alignment Check

Inspect all suspension components for signs of wear or damage; replace any faulty parts.
If alignment is off, adjust alignment settings to manufacturer specifications using an alignment tool.
Torque all suspension components and wheels to the manufacturer-recommended torque specifications.

4. Brake Inspection

Remove the wheel and inspect brake rotors for warping or uneven wear. Replace if necessary.
Clean the brake components and ensure they are functioning smoothly.
